Be it known that we, ALVAH C. ROEBUOK and FRANK MCMILLAN, citizens ofthe U nited States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented certain new and useful Improvements inGenerating Apparatus for Hydrocarbon -Lamps; and we do hereby declarethe following to be a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification.

The present invention relates generally to that class ofhydrocarbon-vapor lamps in which the hydrocarbon vapor as it is diserator draws along with it a proper volume of air into thecommingling-chamber, from whence the mixed air and vapor is carried toan incandescent-mantle burner and by a combination in contact with theburner-mantle effects an incandescent illumination; and the presentinvention more especially relates to that particular type of suchapparatus in which an auxiliaryjet or burner is employed to afford aconstant source of heat to the vapor-generator of the apparatus.

The object of the present improvement is to provide a simple,convenient, and effective construction and arrangement of the generatingand commingling portions of the apparatus whereby a perfect adjustmentof the various parts of the apparatus to suit the varying conditions metwith in use can be effected in a ready, convenient, and substantialmanner, all as will hereinafter morefully appear and be moreparticularly pointed out and set forthin the claims. We attain suchobject by the formation and arrangement of parts illustrated in theaccompanying drawings, in which Figure l is a detail perspective view ofthe generator, commingling-chamber, and connections. Fig. 2 is a sideelevation of a va por generating apparatus embodying the presentinvention; Fig. 3, a transverse sectional elevation at line a; 00, Fig.1; Fig. 4, a detail transverse sectional elevation illustrating theauxiliary burner and its connections. 7

Similar numerals of reference indicate like parts in the differentviews.

Referring in detail to the drawings, 1 rep- I resents the closedreservoir, adapted to contain the supply of gasolene or other lighthydrocarbon liquid; 2, a valved inlet through which a pressure of aircan be introduced into the interior of the reservoir to cause a forcedfeed of the gasolene or other liquid to the vapor-generator, and 3 avertically-an ranged tubular post fixedly attached to the top of thereservoir 1 and having the usual 6 is the horizontally-arrangedneedle-valve, d

by which' the vapor-outlet is regulated and controlled. A 7 is thehorizontally-arranged com minglingtube, one end of which is in line withthe outlet-jet 5, so as to receive the jet of vapor therefrom, while theother end has a suitable hose or other usual connection with an ordinary incandescent mantle -burner. In the present invention a duplexadjustment of the commingling-tube 7 is provided, whereby an adjustmentof the same can be attained to suit any varying requirement that mayarise in the varied applications of the present invention, and suchadjustments will comprise a longitudinal adjustment in a horizontal lineto and from the outlet-jet 5 in order to vary the distance between suchjet and the mouth of the commingling-tube, such adjustment being readilyeffected by means of the guidecollar 8 on the supporting-bracket 9' andthe fastening-screw 10, a vertical adjustment of said commingling-tubein a vertical direction, so as to adjust the same in proper axialalinement with the outlet-jet 5, such adjustment being readily andefficiently elfected'by connecting the bracket 9 to the vertical post 3by a collar 11, so as to be capable of a vertical adjustment thereon,which is in turn effected by means of the vertically-arranged adjustablescrew 12, screwing into the bracket 9, with its lower end hearing orabutting upon the top of the reservoir, as shown, and a swingingadjustment in a horizontal plane, the post 3 constituting the fulcrum ofsuch movement, the parts being held to the required adjustment by aset-screw 13.

The auxiliary burner, by means of which a constant heat is maintainedbeneath the generator or retort 4, comprises in the present constructiona transversely-arranged tube lt, arranged immediately above the retort 4and communicating therewith, so as to receive a supply of vaportherefrom. Such tube 14 is provided at one end with an outlet-jet 15 andat the other end with a needlevalve 16, by which the outlet of vapor iscontrolled.

17 is a tubular segmental comminglingchamber, one end of which isadapted to receive the jet of vapor discharged by the outlet-jet 15,while the other end is adapted to discharge such Vapor commingled withair directly beneath the retort4c and by the combinationof such mixturemaintain the retort or generator at the desired elevated temperature.The segmental commingling-chamber 17 is supported by the tray-shapedbracket 18, attached,by means of its collar 19 and set-screw 20, to thevertical post 3 in a vertically and horizontally swinging manner, so asto attain a proper adjustment of such tray-shaped bracket beneath thegenerator or retort 4. In addition to the adjustments above described ofthe tray-sh aped bracket the segmental commingling-tube is alsoadjustably attached thereto at its outlet end by means of the setscrew21, so as to further aid in the universal adjustment of the parts andthe attainment of the proper relation of such parts one to the other.

The tray-shaped bracket 18 is intended in addition to forming a supportfor the sectorshaped commingling tube or chamber 17 to also perform itsusual function of a preliminary heater for the generator in firststarting up the apparatus, and for this reason is chambered out on topto receive a quantity of liquid combustible, by the combination of whichthe preliminary heating of the retort or generator is effected as usualin the present type of apparatus.

22 and 23 are hoods arranged over the jets 5 and 15 and adapted toshield the same from the flame of the auxiliary burner, so that thevapor will not be ignited at its point of issue vfrom such jets.
